Surface oscillations in channeled snow flows
, 2007 An experimental device has been built to measure velocity profiles and friction laws in channeled snow flows. The measurements show that the velocity depends linearly on the vertical position in the flow and that the friction coefficient is a first-order

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Discrete stochastic modeling of calcium channel dynamics
, 1999 We propose a simple discrete stochastic model for calcium dynamics in living cells. Specifically, the calcium concentration distribution is assumed to give rise to a set of probabilities for the opening/closing of channels which release calcium thereby ...

Modeling of Ion Channels [PDF]
The Journal of General Physiology, 1999 Modeling of biological ion channels has a long history, going back more then 100 yr ([Hille 1984][1]). In the old, premolecular biology era, interpretation of these simple models provided the primary source of information about channel structure.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Security in Cognitive Radio Networks
, 2014 In this paper, we investigate the information-theoretic security by modeling a cognitive radio wiretap channel under quality-of-service (QoS) constraints and interference power limitations inflicted on primary users (PUs).

Models for gramicidin channels
Biophysical Journal, 1992 To the Editor: In several recent papers, NMR results for gramicidin A have been compared with predictions based on various models for a right-handed channel. In particular, 2H quadrupolar splittings (Hing et al., 1990a,b; Prosser et al., 1991) or '5N chemical shifts (Chiu et al., 1991) from solid-state NMR spectra of labeled gramicidin A in oriented ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Modeled channel distributions explain extracellular recordings from cultured neurons sealed to microelectrodes [PDF]
, 2002 Amplitudes and shapes of extracellular recordings from single neurons cultured on a substrate embedded microelectrode depend not only on the volume conducting properties of the neuron-electrode interface, but might also depend on the distribution of ...
